AIR SANDING DEVICE.

To all :whorn it may concern:

lie it known that I, James E. Scones, a citizen of the United Sta es, residing at 648 South Sixth street, east. Salt. Lake City,

county of'Salt. Lake, State of Utah, have invented a new and useful Air Sanding Device, of which the following is a specification.

This invention has reference to sanding devices for electric cars and other railroad vehicles wherein compressed air is used and is desi liedparticularly to construct a tie vice this character, parts of which may be kept in stock at the shop, and readily replace all w'orn elements of the apparatus.

The present invention also contemplates the construction of a sanding mechanism.

wherein the same may be readily cleansed, and all particles of sand solidified by dampnessmay be broken without emptying the box.

\Vit-h the above and other objects in view,

drawings, A indicates in general the sand box of a locomotive provided with two alined openings in the bottom thereof. Through one of said olxenings projects the nipple 10 provided with the threads 11 at-each extremity thereof, the upper extremity of said nipple projecting through the bottom of the sand box A and being retained therein by the clamping nut 12 operating on the threads 11 formed on the upper terminal thereof. The lower extremity of the nipple 10 is connected to the T-joint 13 through the instrumentality of the threads 11 formed on the lower terminal thereof.

()ne extremity of the longitudinally disposed openings of the T-joint 13 has threaded therein the air connection. This air connection comprises the exteriorly threaded nut 14, which secures the connection to the T-joint through the central opening of which Specification of Letters Patent. Application filed July 24,1909. Serial No. 509,470.

extends 'the pipe 15, said pipe being provided with an enlargement 16 adjacentthe nut to more securely retain the same in place. The free terminal of the pipe is curved upwardly and provided with the threads 17 which form a means whereby the same may be connected with an air hose. The opposite terminal 18 of the pipe 15 passes more than half way the passage of the T-joint 13 and is provided at its immedi ate extremity with the removable enlargement 19, said enlargement. having formed therein the centrally disposed air hole 20. A nipple 21 is secured in the opposite extremity of the longitudinal passage of the T-joint 13 and provides a connection between the latter, the outlet and the cleaning line. The free terminal 01 the nipple 21 is connected with the Tqomt 22. the longitudinal passage of sanl T-1onitforunng thceounection between the sand box and the outlet and cleaning fine.

The cleaning llue comprises a pipe or tube 23 connected in the upper terminal of the vertically extending T-joint 22, said pipe projecting through the remaining opening in the bottom of the sand box and extendingnp'a'ardly in such a manuer that the uppei terminal thereof is;adjarent to the top of said box. The upper extremity of the pipe is provided with the threads 24 on which is threaded the cap 25, said cap formiug a means whereby sand is kept from said clearing fine.

The opposite end of the longitudinal passage of the T-joint. 22 has removahly secured therein the outlet pipe 26, said pipe being of such a construction that a flexible hose may be secured thereto in order to conduct the sand from said pipe to the wheel with which the sanding; device adapted to (-oi'iperate.

From the foregoing, it will readily be seen that the sand will drop fr m the sand box through the nipple 10 which comprises a supply pipe to the T-joint 13 and thence to thenipple fil which forms a sand sent. Air in passing through the pi e. 15 and out the air hole 20 forces the sum from the T-joint 13 and the nipple 21 through the nipple 22 to the track through the instrumentality of the out-let 26.

Should any sand become solidified within any of the various elements of the dcvice,the only operation necessary is to remove the cap 25 and insert a rod or similar element into the flue Q3 Wl1lCll will readily loosen the sand.

pirt become worn or rusted, the same may tachablc enlargement at the inner terminal thereof, means whereby the opposite extrem- It will further be noted that, should any 1 readily replaced without removing the rc- Z V maining parts or elementsof the device.

The present invention is readily attached to all sand boxes of an Y OI'tllmlI'" or usual construction, and is securely held in place by the clamping nut 12 and retained from rotation by the cleaning line Having thus fully described my invention, what is claimed as new is:

1. In a device of the class described, the

sand box, means whereby said supply pi ity of said T-joint may be connected to an outlet, and means for cleaning the elements of the device.

5. In a device of the character set forth, in combination with a sand box, of a. nipple projecting through the base of said sand b x, a T-joiut connected with he free terminal of said nipile, a nut threaded in one extremity of said T-joint, an air supply pipe passing throng-.1 said nut and partially through the passage of said T-joint pro- I vided with a detachable enlargenn-nt at its ct'nnbmation with a sand boa, of a supply pipe projecting through the bottom ot said may be clamped in position, a three-wayconnection secured to the tree terminal of said 5 supply pipe, means for injecting air at one extremity of said three-Way connection. and means whereby said connection may be. removably secured to an outlet.

jccting through said sand box whereby the elements of the mechanism may be cleaned.

3. In a device of the class described. the

box provided with threads at each extremity I means for cleaning the elements of the dc- 5 vice.

2. In a device of the class described, the combination with a sand box, of a supply terminal of said nipple. means for injecting air in one extremity of said three-way joint. a nipple detachably secured in the opposite extremity thereof, a similar threeway oint.

Isecnrcd to the tree terminal of tlitl last movably secured to an outlet,and means pro- I named nipple. an outletpipe dctachably sccnrcd in one extremity of the passage of the 4 latter three-way joint. and cleaning means in the opposite terminal of said passage.

combination with a sand box, of a nipple projecting through the bottom of said sand thereof, a clamping nut threaded on tln.-= upper terminal of said nipple and bearing against the inner side of the bottom of said of said T-joint, an air supply pipe passing through said nutand partially through the passage of said T-joint provided with a de- T. ln :1 device of the character set forth, the combination with a sand box, of a nipple projecting through the bottom of said sand box. a three-way joint c nnected to the outer terminal of said nipple. means for injccting air in one extremity of said three-way joint. sand box, a T-joint connected to the opposite i terminal of said nipple, means whereby air 1 may be injected at one terminal of said T- j joint, and means whereby the opposite teriuia nipple dctachably secured in the opposite cxlremit thereof. a similar three-way joint secured to the free terminal of said last named nipple, an outlet pipe dctachably secured in one extremity of the passage of the latter three-war joint. and a cleaning means for the elements comprising a tube secured in the oppo ite extrcmitv of said passage and projecting substantially entirely through said sand box provided with a removable cap at its upper extrcnntv. said nipple. a nut threaded in one extremity JAMES H.
